CHANGEABLE EXHIBITOR.

Application filed August 9, 1e21, Serial My present invention relatesgenerally to advertising devices and more particularly to a changeableexhibitor, my object being the provision of an intermittently movableex-. hibiting device together with means whereby views therefrom may bethrown upon ascreen and whereby proper and unfailing operation isinsured. from connections through a continuously rotating source ofpower as well as whereby to mask the source of light while change ismade from one view to another.

K With these general objects in mind my invention resides in theconstruction, arrangement and operation of parts to be now describedwith respect to the accompanying drawings, which latter form a .part ofthis s e ification and wherein, 'Figure 1 is a side view illustratingthe practicalapplication of my invention,

, Figure 2 is a front elevation of the changeable exhibitor, I o IFigure 3 is a side view thereof, Figure 4is an enlarged side view of afragmentary portion ofthe movable image support, partly broken away andin section, Figure 5 is a plan view of the part shown in Figure 4,

Figure 6 is a partial side view, on an enlarged scale, of theintermittent shifter, partly broken away and in section,

Figure 7 is a detail perspective view of the friction piece shown inFigure 6,

Figure 8 1s a detail perspective view of the friction brake, and

Figure 9 is a detail perspective view of one of the images in its frame.

Referring-now to these figures, my inven tion proposes an arrangementadapted to project images, for instance for advertising purposes, upon aground glass or other screen 10, in a frame 11, by means of a lightbeam, preferably from an electric bulb 12- mounted in a light box 13.The -light box is mounted upon a bracket, 14, and the beams from thebulb 12 proceed forwardly, by virtue of a rear reflector 15 in the lightbox, through concentrating lenses 16 at the forward portion of the lightbox and thence through an image and a projecting lens 17, to the screen10.

The projecting lens 17 is preferably mounted upon a bracket 18, and thebrackets '14 and'18 are respectively connected to and supported by therear and front uprights- 19 and 20 of an exhibitor frame, each. of

No. 490,908.- Renewed October 5, 1926;

which uprights is in form substantially a truncated triangle, itsupperportion supporting a bearing 21 for one end of the axial shaft 22of an enlarged rotating disk-like wheel 23 which constitutes anintermittently rotating image supporting member.

The disk-like wheel 23 has in its forward face an annular series ofsmall apertures 24, the series being arranged concentric therewith andis also provided withan annular series of, large rectangular openingsbeyond the apertures 24 and also concentric with the shaft 22, theopenings 25'extending entirely through the disk or wheel 23 and being incommunication with slots 26 whose outer ends open through theperipheryof the disk as particularly shown in Figure 4. There is thus provided aplurality of radial peripherally opening pockets in the exhibiting diskor wheel for the reception of a plurality of image frames 27, one ofwhich isshownin Fi ure 9, and'e'ach of which is adapted to hol an image28 to be exhibited and has an opening 29 so that when inserted in thepocket 26 the opening 29 registers with an opening in the front face ofthe disk at the same time the image 28 registers with the disk opening25. In the openings of the disk 23 thus registering with the frameopening 29 there is a latch pin 30 whose outer angular portion hasagooseneck curve and aspring tail 31, the latter secured at its extremityto the disk or wheels 23 so that the pin is movable against the tensionof the spring tail when an image frame 27 is inserted'into or removedfrom the respective pocket, and is normally held seated in the opening29 of the frame to prevent the latter from accidental displacement.

The foregoing construction it will be noted leaves the peripheral edgeof the-exhibiting disk or wheel 23 substantially smooth, and

this edge is engaged by aresilient frictional brake piece 32' attachedto and carried by the uprights 19 and 20 as seen in Figures 1 and 2 andshown indetail in- Figure 8. The function" of this brake is to preventaccidental displacement and overrunning of the friction wheel. o v f v 7The uprights 19 and 20 also support a shaft 33 at one side, on which anintermittently operating shifter is mounted. This shifter is in the'formof a disk 34 having a sprocketwheel 35 secured upon its rear face asseen in Figure 6 and-'havinga radial pocket 36 opening through itsperiphery ad:

jacent to its rear face for the reception of a friction plug 37 as seenin Figure 7. The plug 37 has longitudinal slots 38 and through theseslots are extended guide pins 39 fixed in the rotating disk 34 thelatter of which is constantly rotated through a sprocket chain 40engaging its sprocket wheelfll') and extending from a constantly rotateddriven sprocket -11. The friction plug 37 whose outer surface ispreferably convexed as at 42, seated at its inner end against a spring lt; in the pocket- 36 and the rotating disk 34 is mounted in suchproximity to the intermittently rotating exhibitor wheel 23 that thefriction plug 37 yieldingly engages the periphery of the wheel 23 for aportion of each complete rotation of the disk 34.

The constantly driven sprocket 41 is mounted on a shaft 44 in connectionwith a worm wheel 45, the latter of which is engaged by a worm 46 on ash at't 457 having a pulley 48 which is belt connected in practice toany suitable source of power as for in stance an electric motor.

Mounted through a guide opening ofa cross bar 49 of the forward uprightis a latch pin 50 whoserear end is adapted to extend into the aperturesof the series 2st. whereby upon engagement in one of these apertures theexhibitor wheel 23 will be held motionless with one of itseichibitingopenings 25 alined with the ctmcentrating and projecting lenses 16 and17. Pin 50 has: a movable pivot 51 at its forward end with theupper endof a rocker arm 52, fulcruined at 53 and having a movable pivot at itslower end at 5% with one end of a connecting arm 55 whose opposite endispivotally connected to one end of a lever 56.

As shown particularly in Figure 2 the lever 56 is fulcruined at 57 uponthe upper end of a post 58, and its tree end 59 isnormally held in closeproximity to the tor ward surface of the rotating disk 34: by virtue ofa spring (iOconnecting the upper extremity of the rocker arm 52 with thefor ard uprightQO, which also serves to normally hold the latch pin 50in its inner active posit-ion. Onthe forward face of the disk 34 is a.cam or wedge 'shapedprojection 61 which, in the rotation of disk 34,comes into engage mentwith the freeend 59 otlever 56 in each rotationslightly before engagement of the friction plug 37 with the peripheryofthe wheel 23. Thus at the time of engagement of the friction plug withthe exhibitorwheel, lever 56 will have been shifted on its fulcrum 57towithdraw the latch pin50 from an aperture 24: of the exhibitor wheelin order that the latter may be freely rotated to position the nextauccessiveimage in alinemeat with the concentrating and projectinglenses 16 and 17.

As shown in Figure 1.,the light source is preferably in thenature of anelectric bulb 12, whose leads 62 connect with brushes 63 supported forflexible yielding engagement wit-licontact rings 64 and 65 of theforward portion of the disk 34, and one of which rings (is is brokenaway at a recessed portion 66 ot the disk diametrically opposite theplug 37 so that the circuit of the light bulb 12 will thus be broken atthe time the exhibitor wheel 23 is being rotated. For the above purposethe disk 34 will be preferably formed rot nonconducting material, inorder to insulate the rings tl-l and tih from one another, and lightingcurrent from any suitable source may be supplied to the rings 64 and 65in any suitable manner.

Thus in operation with the parts set up in the position shown in Figurel and the images with their frames 27 properly inserted and latched inthe peripheral pockets of the exhibitor whetilQi-B, it will benoted thatcontinuous rotation of the disk 34 serves to bring about partialrotation of the exhibitor wheel at one point in each complete rotationot the disk, namely when the plug 37 yieldingly andplrietionally engagesthe peripheraledge of the wheel. At the time of this engagement thedislflprojection 61 has functioned to withdraw the latch pin 50, thelatter when released 1 being pulled by the spring 60 into engagementwith the face of the exhibitor wheel soas to automatically drop into thenext succeeding aperture 24 as the wheel is rotated. It will also benoted thatat the time the friction plug 37 engages the periphery of theexhibitor wheel 23 for rotation of the latter the lighting circuit ofthe bulb 12 will be broken so that each irotative movement of theexhibitor wheel 23 will be accomplished in darknessand theresult thusthat each successive image of the wheel 23 will be flashed on to thescreen 10 and steadily maintained for an appreciable time, and theflashing on and off ollthe light with the appearance or" a new in'iageeach time the light flashed on thus adds to the attractiveness of thedisplay and to the value of the device especially a when utilized foradvertising purposes. a a
